Funny concept, I love runners and the game is very good, but I thinks the game could be a little bit faster, the art is beautiful, really beautiful pixel art, I loved, the audio is amazing, cool songs so catchy and good sfx, cool game, great job !

It's the way the hero and backgrounds move (although the parallax scrolling looks very nice!). They're "too smooth", i.e. if you took a screenshot, the image wouldn't fit perfectly in a 64x64 grid of pixels, because boundaries are crossed & some cells would contain multiple colors. It's a minor thing! I still gave you 4/5 for Authenticity. :)
